    3. An Overview of Simulated Distillation Methods and Their Application to Petroleum Processes There are a number of ASTM Simulated Distillation Methods that overlap in boiling range  and scope.   In this presentation we discuss the ASTM methods  and their merits and challenges for the analysis of petroleum streams and processes. The critical differences of the methods and the appropriate method for the analysis of process distillates, transportation fuels and whole crudes will be covered. Examples of analysis using the Agilent SimDis Package will be demonstrated.

    4. Refinery Operational Controls Temperature/Pressure/Flow Measurements Cut Point Temperature Cat. Avg. Bed Temp. Recycle Pressure Volumetric Product Yield The Boiling Point is the single control variable consistently applied across all refinery process streams and operations.

    5. The Value of Process Measurements Applications Realized Savings • Crude Unit Monitoring $800K/Mo • LPG Stream Quality $3MM Year • Effluent Monitoring $200K/Day • FCC Operations • Hydrocracking Operations $5MM Year

    6. The Value of Accurate Cut Points Shift of 10°F in Cutpoint is worth $10.00/BBL Yield (Wt %) • Boiling Point (°F)

    7. What is True Boiling Point TBP is term describing the analytical results obtained from the distillation of stabilized crude petroleum to a final cut temperature of 400°C Atmospheric Equivalent Temperature (AET). … This test method details procedures for the production of a liquified gas, distillate fractions, and residuum of standardized quality on which analytical data can be obtained, and the determination of yields of the above fractions by both mass and volume. From the preceding information, a graph of temperature versus mass % distilled can be produced. This distillation curve corresponds to a laboratory technique, which is defined at 15/5 (15 theoretical plate column, 5:1 reflux ratio) or TBP (true boiling point).

    8. True Boiling Point TBP Curve for Distillation of a Whole Crude

    9. True Boiling Point and SimDis of a Whole Crude

    10. SimDis SimDis (short for Simulated Distillation) is a standardized chromatographic method which models the distillation curve of a hydrocarbon mixture and converts retention time to Boiling Point. American Standards and Testing Methods (ASTM)currently uses 6 SimDis methods for a variety of sample types SimDis is the only characterization method capable of analyzing the entire range of volatile hydrocarbons found in petroleum (i.e from n-C3 through n-C120) It is the methodology of choice for the self-consistent analysis of petroleum processes and products.

    11. SimDis-GC SimDis-Gas Chromatography partitions the sample based on the boiling points of the individual compounds contained in the sample. Low boiling compounds (molecules) are eluted and characterized first followed by higher boiling compounds n-C11 n-C20 n-C5

    12. Simulated Distillation SIMDIS is a chromatographic procedure which translates retention time to boiling point….

    14. D2887 SIMDIS Yield % vs BP 60% yield % occurs at 650°F Half a barrel of crude is directly usable as a distillate fuel Boiling point is the one common measurement applicable to all refining process streams SIMDIS information is essential in assigning value to crude and develop refining operating plans Yield % (wt basis)

    37. Fingerprinting Methods Analytical Fingerprinting refers to the characterization of a sample by the use of techniques which use features obtained from the analysis to distinguish differences and similarities among samples and sample types. These methods are generally used to verify specification compliance for select product streams and often to identify the source of “fugitive” hydrocarbons
